The Importance Of Noncapped Viral Genomic Rna To Alphaviral Infection And Pathogenesis., Autumn Lapointe
Electronic Theses and Dissertations
Alphaviruses are mosquito-borne arboviruses that have a positive sense, single-stranded RNA genome, which are capable of causing severe disease and thus pose a significant burden to public health. During alphaviral replication, significant quantities of viral genomic RNAs that lack the canonical alphaviral 5’ cap structure are produced and packaged into viral particles, despite the fact that these noncapped genomes cannot be translated and are essentially noninfectious. The production and packaging of the noncapped genomes has been found to be true for infections across multiple vertebrate and invertebrate cell lines and alphavirus species, although the proportion of ncgRNA produced differs. Despite …

Electronic Theses and Dissertations
Alphaviruses are positive sense, single strand, RNA viruses. These viruses occur on every populated continent. Alphaviruses are divided into two clades, the New-World and Old-World viruses. The New-World viruses include Eastern (EEEV), Western (WEEV), and Venezuelan equine encephalitis viruses (VEEV), and cause neuroinvasive disease. The Old-World viruses include Chikungunya (CHIKV) and Ross River viruses (RRV), and typically cause multijoint arthralgia. There are currently no approved antiviral therapeutics or vaccines for any alphavirus, making them a high priority for antiviral drug design and discovery. A benzamidine inhibitor (ML336) of VEEV was characterized, and determined to inhibit replication of VEEV RNA during …
